7 Specification of Letters Patent, Application filed March 6. 1905. Serial Ito-248,456. i

Patented Nov. 6, 190av To all whom it may concern:

" Be it known that I, ARTHUR S. ALLEN, a citizen ofthe United States, and a resident of Brookline, in the county of Norfolk and State of Massachusetts; have invented an Imowing description, in connection with the ac-' companying drawings, is a specification, like letters on the drawings representing like parts. This, invention relates to wheel-tires of india-rubber or similar yielding -material,

and has for its object to provide the same" with, a puncture-proof armor.

' The invention to be describedis illustrated as an improvement on that described in my previous application forLetters Patent of the United States, Serial No. 232,412, filed November 12, 1 904. The tire shown in saidapplication contains a series of intermeshed wire coils crossing the tire, and the'endsof some of the wire coils are carried into the indie-rubber, acted upon by the rim" of the wheel or that part "of the tire with which coacts whatever is used to retain the tire on the Herein I have extended longitudinally of the tire, along that part thereof at'or about the rim, a series ofintermeshed edge coils that extend circumferentiallv "about the rim. One longitudinal coil of the series of edge-coils is-provided with a cord that is-embraced by stay-cords extended longitudinally through and locking together the intermeshed coils that cross the tire.

I believe that I am the first to combine with an armor of any'sort embedded in the body of the tire a series of intermeshed edge coils surrounding the rim, whether the armor be, as I prel.er, co'mposed of intermeshed wire coils or other armor composed of wire or metal. I also believe that ,I am the first to use in a tire wire covered with textile material, so that the india-rubber applied to the tirewill cling more closely to the armor used. inthe tire."

Fi ure 1, in perspective, shows part of a whee rim and a section of tire provided with intermeshed wire coils in accordance with my in vention, portions of the tire being broken out to show the trend of the diflerent.

layers of wire coils; Fig. 2 is a detail showing some of the intermeshed wire coils that cross the tircconnected with the edge coils that surround the The rim A, having lips A to be engaged by the-hookededges b of the tire B, and the inner inflatable tube 0 are and may be all as usual, the particular shape of 'the' tire in cross-section and the'particular manner of.

attaching the tire to the wheel-rim not being essential, and instead of holding the tire 1n place by the hooked edges of the rim. I may em loy any other usual holding means by" which to retain the tire on the rim. a

The series of intermeshed wire coils e f 9, formed of wires twisted, preferably, right and left, laid side by side, and intermeshed one-with'the other b shovin' the side of one coil into the side of t e other y lateral move ment of one coil with relation tothe other, are and may be the same as'full y described in mv said ap lication, Serial l\o. 232,412.

intermeshed air of wire coils when intermeshed is united ya strand m, and the. wire coil next the.

connection n receives through it a wire 11/. The intermeshed coils f, that cross the tire for more or less of itslength, are united b -a strand 1), the samestrand being ext'en ed through one after theother of the intermeshed coils, and, viewing Fig. 2, it will be seen that the strand p is assed' around the connection n after its wit drawal frombne pair of intermeshed coils and before it is passed through the next pair of intermeshed coils, it being understood that the wire fabric. represented, by the intermeshed coils is built up and made of greater or less lengt by uniting one coil with another or side by side by a strand p. The connection n is united, with the wire 11/ by a bindern, which embraces the connection and also the wire. In this way it will be seen that the armor composedof wire coils that enter into'the indiarubber forming the body of the. tire' is comosed' of two series of wire coils, one extend- I do mg crosswise of the tire and the other run-' ninlgllengthwise of the-tire.

into the thickened par-t ofv the tire edge that is to be engaged by whatever meana is to be 1o 5 is invention snot limited to the parrepresentedat p.

of tires it has been common treads, which are adapted posed. For instance, in Fig. 1 some of theseries of edge coils are bent backwardly, as The interstices of these wire coils, intermeshed and locked together as described, receive a filling, preferably of 'india-rubber or equivalent material, that may be vulcanized after being applied to the interstices of the wire coils. This filling may be applied either before the wire coils are laid into the india-ruhber to form the body of the tire or the interstices may receive the filling during the manufacture of the tire on the usual former, it being understood 'that the body of the tire may be produced by usual means understood by workers in india-rubber and in the usual way.

Adding the edge coils to the transverse coils forms a finish for the armor and makes it possible to form more easily the head at the base of the tire. The invention'her'ein described is applicable not only to tires, but also to so-called to be applied to tires for a thickening therefor.

In the use of wire coils in the manufacture to apply indiarubber compound directly to the wire, and

in my experiments,- aiming to more thor oughly and securely incorporate the wire in the body of a tire, I may and have covered the wire from which the wire coils and strands are made with a non-metallic material which will preferably be composed of fibrous material 12 wound around the wire p,

constituting the core for the coils and the strands. The india-rubher will cling with greater tenacity to the fibrous covering than to the metallic surface of-the wire.- Having fully described my invention, what .I'claim asnew, and desire to secure by Letters Patent, is-

1. A flexible tire comprising a yielding body having an internal metal armor, combined with a series of edge coilsembedded in that )art of said body in contact with the rim of the wheel, and adapted to be extended about said rim in the direction of-its len th.

2. A flexible tire comprising a yiel ing body having an internal armor, and a series of intermeshed wire coils in that part of the body that contacts with the wheel-rim, and adapted to be extended about said rim.

3. A flexible tire comprising a bo'dy havin ,hooked edges, a series of wire coils in sai .body and crossing the same, and other series {of wire eoils running longitudinally in said hooked edge. i I

4. A flexible tire having internal intermeshed wire coils crossing the tire, and a series of connected edge coils adapted to be extended about the rim in the direction of the length of the the 5. A flexible tire having internal intermeshed wire coi'ls'crossing the tire, and a se ing means extended therethrough composed of wire having a non-metallic covering and extended through said coils. I

- '7. A flexible tire composed of wire having a non-metalliccovering and a body of india-. rubher'in which said wire is embedded.

In testimony whereof I have signed'my name to this specification in the presence of two subscribing witnesses.
